Applications were once built on a monolithic structure. Huge teams would work using a single application prototype, which came together quickly, with little maintenance needed. Yet, as the application grows toward production, management gets more difficult to control. As there are multiple layers including the interface, business logic, data interface and data storage, applications need user input, processing, application of business logic, to enrich existing data, and need to be stored for later additional processing. The issues with this type of architecture include:
Let’s explore the concepts of Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS).
SaaS Also known as “cloud application services,” SaaS uses the internet to deliver applications, managed by a third-party vendor. As applications run through a web browser, they don’t require downloads or installation from clients. Businesses use SaaS in several situations, including:
IaaS is a cloud computing architecture that includes servers, network, operating systems and storage, all delivered using virtualization. IaaS clients enjoy complete control of their entire infrastructure, without the need to maintain or manage it. IaaS clients managed some aspects of their own applications, runtime, middleware and data, but often rely on providers for the management of their servers, hard drives, networking, storage and virtualization. A few advantages of IaaS are:
PaaS can’t replace an entire IT infrastructure. It uses a cloud service provider to host the infrastructure, which users access through a web browser. PaaS services include:
Traditional applications offer static linking and business functions. Microservice applications are different in their ability to connect to microservice endpoints for a totally functional application. Setting up the right PaaS means automatic deployment, provisioning and a link to full-stack microservices. The goal is to rapidly quality test and release new versions. These teams use PaaS to simplify all manual management needs and reliability. Because microservices are full-stack silos consisting of things like web servers, databases, load balancers and integration servers.
A microservices is a tiny application that performs one specific function, remaining independent from other services. The application can use any framework or language, and works both on-premises and on public cloud. An easy example is that of a small application run on a compute cluster. If it runs on 5 cluster, and one fails, the other 4 clusters will maintain the integrity of the application and ensure it continues to operate normally. The benefits of a microservices-oriented architecture include:
Teams go with a microservices design approach that divides business solutions into sperate, full-stack services managed by independent teams. They can also approach the issue by joining many different microservices for a more holistic user experience More traditional delivery and infrastructure don’t work well in this situation. Luckily, platform-as-a-service steps in at this point to lessen fragility, reduce operational requirements and enhance productivity.
A recent article by Hackernoon says, “Containerization involves bundling an application together with all of its related configuration files, libraries and dependencies required for it to run in an efficient and bug-free way across different computing environments.” The popularity of microservices has spawned the construction of a meshwork of services, which is “a configurable, low‑latency infrastructure layer designed to handle a high volume of network‑based inter process communication among application infrastructure services using application programming interfaces (APIs).”
Kubernetes were released inn 2014 to help deploy and managed microservices on the cloud. While most new businesses are using this as a go-to for their start-up, many established businesses are focused on catching up and updating to gain these capabilities
As we’ve noted, PaaS is great for businesses interested in running microservices and using kubernetes. K8s are helping enable a more event-driven architecture for our data. Customers expect real-time updates and notifications, and the rapid availability made possible with microservices means information and applications are pushed faster, with the least amount of friction possible. The easy answer to this question, is “anyone who needs their business processes to be stronger, faster and more secure.
